T0 f//ZZ 1072/0711/ t mrtg/concern:

Be it known thatI, I-IENRY L.y WHITMAN, a

citizen of the United States of America, re-

siding in the city of St. Louis and State of Missouri., have inventedcertain new and useful Improvements in Ealing-Presses, of`

which the following is a full, clear, and eXact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

My invention relates to an improvement in that class of baling-pressesused for baling hay or other materials, the present improvements havingmore particular reference to a novel form of power mechanism and meansof connection between the `power mechanism and the plunger of the press,also to an extensible framework in the press, whereby the parts may beadjusted into a contracted condition when the press is not in use landis being transported from place to place and into an extended conditionto furnish ample sp ace between the power mechanism and thebaling-.chamber for the passage of the draftanimals attached to thesweep of the press for the operation of the power mechanism,

also to certain other details of construction of the press, as willhereinafter appear.

Figure I is a side elevation of my press with the frame members inextended condition.'

members in retracted position and the press proper supported by thetruck-wheels utilized only when the press is being transported. Fig. IVis an enlarged top or plan view of the power end of the press. Fig. V isa side elevation of the power end of the press. Fig. VI is an enlargedvertical longitudinal section taken through the baling-chamber end ofthe press, partly broken out. FigVII is an enlarged horizontal sectiontaken through the baling-chamber end of the press, partly broken out.Figs. VIII to X, inclusive, are diagrammatical views illustrating themovement of the power-head of the press and the pull-rod-operating leveractuated by said power-head.

1 designates the baling-chamber of my press, which is mounted uponsupporting-sills 2, that constitute parts of the press-frame.

3 are power-mechanism-supporting sills which are locatedbeneath thebaling-chamber sills and are susceptible of movement in a longitudinaldirection beneath said balingchamber sills.

4 are upper brackets-secured to the balingchamber sills. (See Figs. I toIII, inclusive.) These upper brackets are provided withoutwardly-projecting wings 5, and each wing is f provided with abolt-receiving hole.

6 and 8 are lower brackets secured to the power-mechanism sills 3 atdistances from each other and provided with laterally-eX- tending wings7 and 9, respectively, containing bolt-receiving holes. When the pressis to be put into operation, the power-mechanism sills `3 are drawnforwardly into the eX- tended position (illustrated in Figs. I and II)and bolts 10 (see Fig. II) are inserted through the wings 5 and 7 ofsaid upper and lower brackets 4 and 6,l respectively, which mate witheach other at this time, therebyconnecting the baling-chamber sills 2lto the power-mechanism sills 3. When the press is to be transported,the power-mechanism sills 3 are retracted beneath the baling-chambersills and the lower brackets 8 are thereby brought into mating positionswith the'upper brackets 4, as seen in Fig.' III, after which the bolts10 are inserted through the wings 5 and 9 of said mating brackets 4 and8, respectively, to' hold the upper and lower sills in united condition.

11 are guides iiXed to one set of the sillsfor instance, thebaling-chamber sills 2-and by which the movement of the otherpowermechanism sills 3 is directed when the powermechanism sills 3 arebeing withdrawn or retracted beneath the baling-chamber sills.

12 are truck-wheels on which the press is supported when beingtransported and which are removed when the press is to be put into usefor baling operation in order that the press may be located as close tothe ground as possible.

' 13 designates a bed-plate mounted upon the power-mechanism sills 3.

14 is a post rotatably mounted on the' bedplate and bearing at its upperend a sweephead 15, to which is connected the sweep 16 and sweepbrace-rod 17. (See Figs'I to III, inclusive.)

18 designates a power-head of peculiar construction that is carried bythe rotatable post IOO 14 and is adapted to partake of the same movementas that imparted to the sweephead 15 during the operation of the powermechanism. This power-head is provided at its ends with arms 19, havingdepending pins to which antifriction-rollers 2() are journaled. Thepower-head is also provided with approximately right-angle dependinginwardlyprojecting cams 21, extending from above the rollers 20, beneaththe arms, across the power-head to the opposite corners of the latter,the diverging working faces of which are at their inner sides-in otherwords, at the sides which face the power-head-supporting post 14. Thecams 21 are located nearer the axis of the power-head 18 than therollers 20, and they are adapted to operate upon a pullrod-operatinglever 22 to draw the pull-rod in contradistinction to pushing it, ashereinafter more particularly referred to, after said lever has beenoperated upon by the rollers 20.

22 designates the pull-rod-operating lever pivoted at one end to thebed-plate 13. The lever 22 is provided with an outer or rearbearing-face 23, that is adapted to be engaged by either of theantifriction-rollers 20, carried by the power-head 18. Mounted upon apin at the free end of the lever 22 is an antifriction-roller 24, whichis adapted to be engaged by the power-head cams 21 after a partialmovement has been imparted to said lever through the medium of either ofthe antifriction-rollers 20 during the rotation of the power-head. rfheroller 24 is mounted between the upper side of the lever 22 and anoverhanging yoke-arm 25, which is preferably integral with said lever.Secured to the lever at its under side is a strap 26, between which andthe lever the forward end of a pullrod member 27, leading to the plungerof the press, is held. The antifriction-roller 24 and the forward end ofthe pull-rod are secured to the free end of the lever 22 by a bolt 28,passing through said lever and through the yoke- `arm 25 and strap 26.

In the operation of the power mechanism the antifriction-rollers 20,carried by the power-head 18, operate in turn against the bearing -face23 of the pull-rod -operating lever 22 during each complete rotation ofthe power-head and by so operating act to impart a forward swingingmovement to said lever, thereby causing it to exert a pull upon thepull-rod member 27. Each antifrictionroller 20 acts upon the lever 22until said lever is moved from the position illustrated diagrammaticallyin Fig. VIII to the position illustrated diagrammatically in Fig. IX,and when the power head and lever of the mechanism have reached theposition in the last-mentioned figure the antifriction-roller 24,carried by said lever, has been moved into juxtaposition with the outerend of the power-head cam 21, located at the end of the power-headcorresponding to that which carries the antifriction-roller 20, that isin action against the lever 22. The cam 21, just referred to, thenimpinges against the antifriction-roller 24, and as the power-headcontinues its rotation said antifriction-roller is caused to ride alongthe inside face of said cam, with a result of continuing the operationof the lever 22 through the medium of the power-head. This actuation ofthe lever is continued until the antifriction-roller 24 andpull-rod-operating lever reach the position illustrated diagrammaticallyin Fig;

X, the position of these parts, as there shown, being the maximum oftheir forward movements. As the power-head continues itstravel theantifriction-roller 24 rides off of the cam 21 and the lever 22 ispermitted to return to its former position and carries the pull-rod withit. It is to be noted that the cams 21, being located nearer the axis ofthe power-head 18 than the antifriction-rollers 20, an increase of poweris obtained, while the lever 22 is being operated through the medium ofvsaid cams over that which is obtained while said antifriction-rollersare operated against said lever. As a consequence a rapid movement isimparted to the lever during the period that the antifrictionrollers arebearing thereagainst, and a more powerful operation of the lever isobtained during the period that the cams are operating against thelever, so that the pressing action upon each charge of the materialbeing baled increases in degree as the plunger of the presss is movedforwardly, due to the connection between it and the pull-rod member 27.

29 is a spring-controlled bumper located at the rear of the lever 22 ina housing 30and adapted to receive the impact of said lever and projectinto a slight recess or depression in the outer or rear bearing-face 23when the lever returns to its normal position after it is operatedthrough the medium of the power-head, thereby providing for thecushioning of said lever and the avoidance of shock to the lever and theparts connected thereto.

The plunger of my press is located at the extreme rear end of thebaling-chamber 1 and is adapted to move forwardly in said chamber forpressing action instead of rearwardly for pressing action, as usual inbalingpresses.

31 is the head of my plunger, which is carried by a frame 32, that isguided upon track-rails 33, preferably of angle form in cross-section,and which are located at the bottom of the baling-chainber.

34 is a block or yoke secured to the lower portionof the plunger-frame32 and provided IOC with laterally-extending arms 35, to .which to theframe of the press-plunger, and this pull-rod is composed of varioussections to provide flexibility therein that is necessary due to themovement of the plunger being a reciprocatory one and the movement ofthe pull-rod-operating lever being a rocking one.

27 is the rear section of the pull-rod, which is pivoted at 37 to theplunger-carried block 34 at its rear end. (See Figs. Vl and VH.)

. Located between the forward or main member of the pull-rod are thefollowing parts:A

27L are links connected to the forward end of the pull-rod section 27',and 27b is an intermediate link pivoted to the links 27a and havingjournaled thereto upper and lower antifriction rollersy 27 C. 27d areforward links pivotally connected to the intermediate link 27b and alsoto the rear end of the forward or main pull-rod member 27. Theforwardlinks 27cl are provided with a plurality of staggered pin-holes27?, either of which is adaptedv to receive the pin or bolt 27f, thatconnects the forward pull-rod member to said links,.thereby providingfor adjustable attachment betweensaid parts in order that the` entirepull-rod may be lessened or increased in length, according to themovement it may be desired to impart to the plunger of the press. Theantifriction-rollers 27C are inclosed within a funnel-shaped guidecasing38, by whichthe flexible members of the pull-rod are directedduringtheir movement, said casing being madefunnel-shaped for thepurpose of permitting freedom of movement of said parts to a limiteddegree.

The elasticity in the hay orother materials being baled is sufiicient'in some instances tocause rebound of the plunger after each pressingaction; but to provide for the positive return ofthe plunger after itsforward and pressing movement `has taken place l. utilize retractingmeans that will now be described: 39 are legs depending from fixedportions of the press and in which is. sup orted a cross-rod 40. (SeeFigs. l, lll, V and VH.) 41 are retractile springs each having one' ofits ends attached to said cross-rod and its other end attached to acollar 42, mounted in a fixed position on the pull-rod of the press,this collar being preferably applied to the rear pull-rod section 27.When the pull-rod is drawn forwardly under the action of itsoperatinglever 22, the springs 41 are expanded to a degree sufficient topermit the desired forward movement of the press-plunger, and when thepull-rodoperating lever is` freed in the manner described the springsact to return the plunger, the pull-rod, and the pull-rod-operatinglever to their normal positions.

For the purpose of cushioning the pressplunger upon its rearwardmovement to avoid shock thereto I provide the following parts: 43 areboxes rigidly mounted at the side of the baling-chamber. 44 are rodsloosely mounted in the boxes 43, and in the rear ends of which ismounted a bumper-rod 45, that is adapted to be struck by an uprightmember 32 of the plunger frame. The vrods 44 have applied to them withinthe boxes 43 one or more nuts 46, between which and the rear ends of theboxes are cushionsprings 47. It will be seen that when the plungerreaches the rear end of its stroke its frame will come in contact withthe bumperrod and cause the rods 44 to be drawn rearwardly and thesprings 47 to be compressed and cushion the plunger in a manner toprevent sudden shock thereto on the completion of its rearward movement.

One feature of my baling-press to which l wish to direct particularattention is that of the plunger of the press being located in andoperating through the rear end of the balingchamber and the pull-rod bywhich the plunger is operated being connected to said plunger entirelyexterior of the baling-chamber, thereby avoiding the necessity of anychannel or slot in the bottom of the baling-cham.- ber through which theconnection between the plunger and the pull-rod operate.

l am aware that baling-presses have heretofore been constructed in whichthe plunger operates in the rear end of the baling-chamber and thepull-rod is attached to the plunger by a connection that works throughthe chamber; but this form of construction is objectionable for thereason that the balingchamber is weakened, due to the presence of theslot therein, and, moreover, it is necessary to provide plates at thesides of said channel, which adds materially to the expense of theconstruction of the press, all of which is eliminated in myconstruction.

Another feature of my press to which I wish to direct attention is thatof the springcontrolled bumper 29 being located in such a positionrelative to the lever 22 that its lever, receiving face faces thepivot-point of said lever, thereby causing the force of the blow betweensaid lever and bumper to be directed toward said pivotal point asdistinguished from the force of the blow being directed at an angle tosaid point. This feature is valuable in that it prevents the bumper fromcausing rebound of the lever.
